KAMLOK COUPLER Dust Cap Aluminum alloy

Hoses for factory equipment and couplings built into machinery

This KAMLOK is a coupling that's installed to the KAMLOK adapter to prevent contamination.

KAMLOK is a coupling composed of coupler (female) and adapter (male) that can be easily installed and removed by tightening or loosening the arm (lever). KAMLOK is available in models that connect to hoses, devices, equipment and piping materials.Aluminum alloy, stainless steel, and polypropylene types are also available to meet various applications, fluids and usage conditions.

Important

*We recommend using couplers and adapters made of the same size and material when connecting fittings. Using couplers and adapters made of different materials may lead to corrosion (electrical corrosion).
*Do not use the dust cap for pressure-resistant applications.

Gasket(equipped as standard): Buna-N(NBR)
Gasket can be selected according to fluid.

Material / Service

Feature:

  • Easy to attach and remove

    The cam arm design makes it easy to attach and remove the coupling, improving operability

  • Resistant to vibrations for safe operation

    The coupler model is vibration-resistant to keep the cam arm from coming off for safe operation.
